Abstract

This study investigated the Effect of Test Length and Ability distribution form on The Estimation of a person's Ability, item difficulty, and the information function of test and its items, According to Rasch Model in Item Response Theory (IRT). Among the procedures of the study was to generate data and items were also generating the examinee's ability, the generated data rate (1000) were examined, for all variables; test length (30, 60) item, and Ability distribution (normal, positive and negative skewed) according to Item Response Theory Models (one-parameter). According to the analysis of data depending on the softwares (BILOG-MG), (WINGEN) and (SPSS), The results showed that there were statistically significant differences at (α=0.05) among the standard error means of item in the estimation of difficulty parameters, such estimations in a person's ability were more accurate in the positive and negative skewed. The test consisted from 30 items. Also The results showed there were statistically significant differences (α=0.05) among the standard error means of item in the estimation of difficulty parameters for the test consisted from 30 items, which provided the most information. The researcher recommends further research depending on other parametric models, also by using real data.

الملخص

هدفت الدراسة الحالية للكشف عن أثر طول الاختبار وشكل توزيع القدرة في تقديرات القدرة للأفراد، وتقديرات معالم الصعوبة للفقرات، واقتران المعلومات للفقرات، وفق نموذج راش في نظرية استجابة الفقرة. ومن ضمن إجراءات الدراسة تم توليد البيانات، ومجموعة الفقرات، وقدرات الأفراد؛ إذ تم توليد بيانات بواقع (1000) مفحوص، بطول الاختبار (30,60) فقرة، وشكل توزيعات القدرة (ملتو التواءً سالباً، طبيعي، ملتو التواءً موجباً)، وفق النموذج الأحادي المعلمة. تم تحليل البيانات المولدة باستخدام البرمجيات (BILOG-MG)، ((WINGEN و(SPSS). أظهرت النتائج وجود فروق ذات دلالة إحصائية (α= 0.05) بين متوسطات الأخطاء المعيارية في تقديرات معالم قدرة الأفراد تعزى لشكل توزيع القدرة ولطول الاختبار، حيث كانت تقديرات قدرة الأفراد أكثر دقة لصالح شكل الالتواء السالب والموجب. ولطول الاختبار (30) فقرة. كما أشارت النتائج إلى وجود فروق ذات دلالة إحصائية في تقديرات معلم الصعوبة وكانت النتائج لصالح الاختبار بطول (30) فقرة؛ إذ زود بمعلومات أكثر. وتوصي الباحثة بإجراء المزيد من البحوث باعتماد النماذج المعلمية الأخرى، واستخدام بيانات حقيقية.
